如何通过ConfigurationManager写入User.Config文件？

Question

我正在尝试使用ConfigurationManager将用户设置保留到配置文件中.

我想将这些设置仅限于用户,因为没有管理员权限,无法在Vista/Win 7上保存应用程序更改.

这似乎得到了用户的配置,它似乎保存在Win 7中([Drive]:\ Users\[Username]\AppData\Local\[ApplicationName]\[AssemblyName] [hash]\[Version \]

Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.PerUserRoamingAndLocal);

每当我尝试将任何更改保存到此配置时,我都会遇到以下异常:

InnerException: System.InvalidOperationException
Message="ConfigurationSection properties cannot be edited when locked."
Source="System.Configuration"
StackTrace:
    at System.Configuration.SectionInformation.VerifyIsEditable()
    at System.Configuration.MgmtConfigurationRecord.GetConfigDefinitionUpdates(Boolean requireUpdates, ConfigurationSaveMode saveMode, Boolean forceSaveAll, ConfigDefinitionUpdates& definitionUpdates, ArrayList& configSourceUpdates)

我尝试将自定义ConfigurationSection添加到此配置中.我已经尝试添加到AppSettingsSection.每当我调用config.Save()它时抛出上面的异常.

有任何想法吗？

我尝试通过Project-> Settings设计器使用ApplicationSettingsBase类,但似乎不能保存自定义类型.我想要类似的功能,能够保存自定义类型.

您需要为该部分设置SectionInformation.AllowExeDefinition值:

 Configuration configuration = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.PerUserRoaming);
UserSettings settings;
if ((settings = (UserSettings)configuration.Sections[GENERAL_USER_SETTINGS]) == null)
{
      settings = new UserSettings();
      settings.SectionInformation.AllowExeDefinition =   
                 ConfigurationAllowExeDefinition.MachineToLocalUser;
      configuration.Sections.Add(GENERAL_USER_SETTINGS, settings);
      configuration.Save();
}

默认值为ConfigurationAllowExeDefinition.MachineToApplication,它只允许将该部分放在machine.config和app.exe.config上.
